Narrative:The TC-47B departed Cali at 12:00 and had just passed the Marmato beacon when a no. 2 engine failure caused the cowling to detach partly, brushing against the propeller. Attempts to feather the prop, accompanied by heavy vibrations, failed at first. When a fire started in the engine, it was successfully shut down and the prop feathered.A forced landing was then made on a ploughed field.

The airplane was reportedly repaired and bought by the Colombian Air Force before it was lost in an accident on July 30, 1979.
